The laboratory performed analysis <br />via EPA Method TO -15 using GUMS in the full scan mode. <br />This workorder was independently validated prior to submittal using 'USEPA National Functional Guidelines' as <br />generally applied to the analysis of volatile organic compounds in air. A rules -based, logic driven, independent <br />validation engine was employed to assess completeness, evaluate pass/fail of relevant project quality control <br />requirements and verification of all quantified amounts. <br />Receiving Notes <br />There were no receiving discrepancies. <br />Analytical Notes <br />There were no analytical discrepancies. <br />Definition of Data Qualifying Flags <br />Eight qualifiers may have been used on the data analysis sheets and indicates as follows: <br />B - Compound present in laboratory blank greater than reporting limit (background subtraction not <br />performed). <br />J - Estimated value. <br />E - Exceeds instrument calibration range. <br />S - Saturated peak. <br />Q - Exceeds quality control limits. <br />U - Compound analyzed for but not detected above the reporting limit, LOD, or MDL value. See data <br />page for project specific U -flag definition. <br />UJ- Non-detected compound associated with low bias in the CCV <br />N - The identification is based on presumptive evidence. <br />File extensions may have been used on the data analysis sheets and indicates <br />as follows: <br />a -File was requantified <br />b -File was quantified by a second column and detector <br />rl-File was requantified for the purpose of reissue <br />Page 3 of 18 <br />
